COMBINED WINDOW VENTILATOR AND SASH FASTENER Filed Aug. 13, 1931 Patented Apr. 1s, 1933 PATENT leuries ADOLF Gr. EYRIN G, OF PITTSBURGH, PENNSYLVANIA COMBINEDVINDOW VENTILATOR AND SASH FASTENER Application filed August 13, 1931. Serial No. 556,885.

This invention relates tofbuilders hardware and more particularly to a window sash fastener by means of which window sashes may be securely held in adjusted posii' "3 tions.

` One object of the invention is to provide a device of this character consisting of companion elements intended to be applied to upper and lower sashes of a window and by means of which the sashes may be firmly se- Y cured in a closed position or the upper sash partly lowered for'ventilating a room and firmly secured in an adjusted position. Therefore a window may have its upper sash M lowered a short distance in order to ventilate a room and a person will be prevented from lowering the upper sash its full extent or raising the lower sash and entering the room.

Another object of the invention is to provide a device of this character having an improved type of plunger carried by the lower sash and an improved type of socket embedded inthe upper sash, the socket being so constructed that the plunger may easily move into the socket and be guided into the same when the upper sash is lowered.

y The invention is illustrated in the accompanying drawing wherein:

Figure lis a perspective view of a window having securing means of the improved construction applied to its upper and lower sashes,

Figure 2 is an enlarged fragmentary sectional view taken through .the upper and lower sashes along the line 2 2 of Figure l,

Figure 3 is a sectional view taken along the line 3-3 of Figure 2, and

Figure t is a. view similar to Figure 2 showing a modified construction.

The window shown in Figure l and indicated in general by the numeral l is of a conventional construction and has upper and lower sashes 2 and 3 which are slidably mounted in guides formed in the window frame for movement into and out of a closed position.

In order to releasably secure the sashes in a closed position and also permit the upper sash to be partly lowered and releasably se- 50 cured in an adjusted position as shown in Figure 1 there has been provided securing means consisting of a plurality of sockets a embedded in theupper sash one above another and a latch 5 passed through an upper corner of the lower sash and engageable in a 55 selected socket of the upper sash. Therefore the two sashes may be firmly secured in a closed position or the upper sash may be lowered a short distance and firmly secured in this position.' When so secured, a room 60 may be ventilated', but the sash will` not be open a sucient distance to permit a person to entera room through the window and it will also be impossible to release the latch while standing outside the window.

VThe sockets are of duplicate construction and each has a tubular body or barrel 6 which fits snugly into a socket or seat 7 bored into the sash. At its inner end thel barrel is formed with a head 8 having a centrally located opening to receive a securing screw 9. A pad 10 formed of rubber fits within the inner end portion of the barrel and is formed with a fastener receiving opening register ing with the opening in the head of the barrel.

Therefore the screw 9 serves to retain the pad in its proper position in the inner end of the barrel as well as serving to firmly hold the barrel in the socket or seat 7. ltl should be noted that the pad isV formed with a marginal flange which projects beyond the head of the screw 9 thereby permitting the pad to serve as a cushion for engagement by the outer end of the plunger l1 forming part of the latch 5 and also preventing this plunger from striking the screw and causing the screw to work loose. f

At its outer end the barrel is provided wit a collar or mouth l2 which flares outwardly and is substantially eliptical in shape with its greatest dimension extending vertically of the sash. This mouth tapers towards the barrel and therefore when the upper sash is slid towards a closed or an opened position, the plunger 11 will be guided into position to enter a socket and if `the sockets are not mounted in exact alignment, one above another, movement of the plunger into a desired socket will be easy to accomplish. The

inner end of the plunger is beveled as shown at 13 thereby making it easier for this end of the plunger to enter a socket.

In order to mount the latch, an opening 14 is bored through an upper corner portion of the lower sash and the plunger extends through this opening with its inner and outer end portions normally projecting from the opposite ends of the opening.

A sleeve 15 carrying a face plate or collar 16 fits within the lopening 14 where it is firmly secured by screws 17 passed through openings formed in the face plate and about the intermediate portion of the plunger is disposed a coiled spring 18 having one end thereof bearing against the inner end of the sleeve and its other end bearing against a washer 19 which lits about the plunger and bears against the bent ends 20 of a pin 21 passed diametrically through the plunger. It will thus be seen that the spring will serve to yieldably retain the plunger in an operative position and cause it to move easily into a socket when the upper sash is raised or lowered.

The outer end portion ofthe plunger is roughened as shown at 22 thereby permitting the plunger to beeasily grasped and drawn to a retracted position. By exerting pulling action upon the plunger after retracting it, the upper sash may be fully closed or opened a distance greater than the distance between one socket and another. As soon as the upper sasn has been moved to approximately the desired position, the plunger may be released and the spring will cause it to move outwardly towards an extended position and enter the desired socket in order to firmlyl secure the upper sash in a fully closed or partly opened position.

lllhen the sa'shes are secured as shown in Figure 1, the upper sash will be held opened a short distance or this sash moved to a closed position and the lower sash secured in a slightly raised position. If so desired, the two sashes may be moved as a unit and each opened a short distance, but in either case, the space between a sash and the window frame will not be sutliciently large to permit a person to enter a room and since the latch may not be reached by a person vstanding outside the window it will be impossible for a person standingoutside a window to release the latch and open the window a suliicient distance to enter the room.

In Figure 4 there has been shown a modified construction. In this form the sockets 23 are similar to the sockets 6 except that they are not provided with iiared mouths. It should be noted, however, that about their open ends the sockets are formed with beveled edge faces 24 in order that the plunger 25 may easily enter a socket. The plunger has its inner end beveled as shown at p 26 in order that it may be easily guided into a socket. Screws 27 are employed to secure the sockets in seats 28 bored in the upper sash but pads are preferably not provided in the inner ends of these sockets.

The plunger 25 slides through a sleeve 29 corresponding to the sleeve 15 and while a spring corresponding to spring 18 has been omitted, a. pin 30 corresponding to the pin 21 is employed in order to engage the inner end of the sleeve and prevent the plunger from being drawn entirely through the sleeve and opening 31 when the plunger is moved to a retracted position.

When this form of latch is used, the operation is the same as that previously described except that pressure must be applied to the plunger in order to move it into a socket.

lVhat is claimed is:

A window having a frame and upper and lower sashes slidable vertically in said frame,

a latch in an upper cornerl portion of the lower sash having a plunger extending through the sash, a series of independent sockets embedded in the upper sash and each having its outer end open and provided with a circumferential substantially Aelliptical shaped end plate countersunk in the face of the upper sash and disposed in longitudinal alinement with the end plates of adjacent sockets, each end plate having its major axis' extending in the direction of the length of said upper sash and inclined inwardly from each end thereof towards the adjacent socket, each socket being provided with a head formed with a central opening, the plunger being of uniform cross sectional diameter throughout its entire length and adapted to successively enter the sockets and bear snugly against the interior walls thereof, a pad bearing against the head of 'each socket7 and fastening devices passing through the pads and openings in the hea s to secure the sockets and pads in place, each pad having a marginal fiange projecting towards the open end of the adjacent socket beyond the fastening device and serving to prevent the plunger from striking the fastening devices when successively moved into the sockets to secure the upper sash in an adjusted position. v y

In testimony whereof I affix my signature.
